The invention relates to a scanning apparatus for scanning information in an information carrier comprising a plurality of layers for storing data on a material capable of generating an excited radiation when interacting with an exciting beam produced by an exciting source. The backboard includes a firm backing layer underlying a soft deadening layer. The vibrating element 6 includes a first piezoelectric element 62 that undergoes extension and contraction by application of an AC voltage, a reinforcing plate 63 having a contact portion 66 and an arm portion 68, and a second piezoelectric element 64 that undergoes extension and contraction by application of an AC voltage. The resulting structure is cohered and monolithic.
